First, let me say this; I have nothing against masochists, sadists or other fetishes and I'm not trying to bash them specifically.

That said, this is not a very good manga. The plot is only there to setup kinky sex play scenes and the character personalities are contradictory at times. Theres no character development whatsoever and the comic relief, the anonymous crowd of male high school students, is more annoying than entertaining due to the (relatively) large number of scenes they appear in.

Read the first few chapters, looks promising... the only problem I had with it would be the actions the main character did at the beginning-- I really hate people that do stuff like that. Regardless it looks like a more refreshing Nana to Kaoru... except the male is the one being dominated O.o...
